Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.

With CONFIG_THERMAL=m, a built-in aspeed pwm tacho driver causes a link error: drivers/hwmon/aspeed-pwm-tacho.o: In function `aspeed_pwm_tacho_probe': aspeed-pwm-tacho.c:(.text+0x7f0): undefined reference to `thermal_of_cooling_device_register' This adds a dependency similar to what other hwmon drivers use, ensuring that the aspeed driver cannot be built-in in this case but has to be a module. With THERMAL=n, we still allow building it. Fixes: 2d7a548a ("drivers: hwmon: Support for ASPEED PWM/Fan tach") Signed-off-by:Arnd Bergmann <arnd@arndb.de> Signed-off-by:
